Abstract

The invention relates to the field of pigment and color paste used for leather and particularly relates to a polyurethane leather coloring agent and a preparation method thereof. The invention aims at providing an artificial leather coloring agent which is high in tinting strength, low in cost, good in stability, weak in volatility, light in solvent taste, less in air pollution and environmentally-friendly. The technical scheme of the invention is to provide a polyurethane artificial leather coloring agent which is prepared by raw materials according to the following parts by weight: 10-30 parts of propylene glycol methyl ether acetate, 15-45 parts of diacetone alcohol, 5-15 parts of PU (polyurethane) anti-yellowing resin, 3-9 parts of bentonite, 10-60 parts of toner, 0.5-1.5 parts of dispersant, 0.1-0.3 part of flatting agent and 0.1-0.3 part of defoaming agent. According to the invention, propylene glycol methyl ether acetate and diacetone alcohol are used for replacing traditionally used organic solvents with higher toxicity, strong smell and high volatilization speed, so that the prepared polyurethane artificial leather coloring agent is high in product tinting strength, low in cost, good in stability, weak in volatility, light in solvent smell and less in air pollution, thus belonging to environment-friendly artificial leather color paste.

Description

technical field [0001] The invention relates to the field of pigment paste for leather, in particular to a colorant for polyurethane artificial leather and a preparation method thereof. Background technique [0002] At present, the domestically produced polyurethane (polyurethane) leather colorant (PU color paste) uses a low boiling point solvent as a dissolution medium. Most of the organic solvents in this series are: Dimethylformamide (DMF), Cyclohexanone (CY), Acetone (ACT), Butanone (MEK), Toluene (TOL), all of the above organic solvents have fast volatilization speed , low boiling point, strong odor, high toxicity, and great harm to the human body. It is mainly manifested in strong irritation to the human respiratory tract, and when the air circulation is not smooth, severe cases may cause coma and shock. Long-term exposure will damage the liver and kidneys of the human nervous system, and it will also spread through the air. It will pollute the surrounding environmen...
